When I lived in Colombia, we had a little room with a washstand for washing clothes by hand a small washer and clothes lines set up indoors (we lived in a condo on the 7th floor). There was a good breeze and our clothes dried quickly. Many apartments are built with having a laundry area in mind, and they are quite efficient about it. Almost no one has a dryer.
In the US it is a different story, we would be able to hang out wash here if we wanted to (no rules against it), but we don't have a backyard that would allow us to do so. I do hang some items up in the laundry area of my house, but we have a dryer for the heavier and more often used items. I can't bring myself to hang the laundry in the front yard, which would be the only other option.
